Two component sensor histidine kinase DosT; Interacts with the two-component regulatory system DevR/DevS (DosR/DosS) involved in onset of the dormancy response. Required for full induction of the DevR (DosR) regulon; required during early adaptation to anaerobiosis, to start induction of the DevR regulon. May act as a direct hypoxia/oxygen sensor. O(2) acts as a switch, with the Fe(2+)-O(2)-bound protein inactive in autophosphorylation. Autophosphorylates under anaerobic but not aerobic conditions, binding of NO or CO has no effect on autophosphorylation. Binds a number of gases; O(2), [...]

Two component sensor histidine kinase DevS; Member of the two-component regulatory system DevR/DevS (DosR/DosS) involved in onset of the dormancy response. Regulates an approximately 48-member regulon. Required for full induction of the DevR (DosR) regulon; acts later than DosT to positively regulate expression of the DevR regulon during adaptation to anaerobiosis. Characterized as an oxygen sensor; O(2) acts as a switch, with O(2)-bound Fe(2+) protein inactive in autophosphorylation. Has also been suggested to act as a redox sensor, or perhaps as a dual oxygen/redox sensor. Autophosph [...]

Sensory transduction protein RegX3; Probably forms part of a two-component regulatory system RegX3/SenX3.

Probable transcriptional regulatory protein (probably TetR-family); Rv3208, (MTCY07D11.18c), len: 228 aa. Probable transcriptional regulator, TetR family, equivalent to Q9CCH0|ML0815 putative TetR-family transcriptional regulator from Mycobacterium leprae (228 aa), FASTA scores: opt: 1248, E(): 1.4e-74, (82.4% identity in 227 aa overlap). Also highly similar to Q9FBI8|SCP8.33c putative TetR-family transcriptional regulator from Streptomyces coelicolor (213 aa), FASTA scores: opt: 629, E(): 4e-34,(45.8% identity in 203 aa overlap); Q9KIL9|F58R F58R (fragment) from Streptomyces coelicolo [...]

Probable alternative RNA polymerase sigma factor (fragment) SigJ; Sigma factors are initiation factors that promote the attachment of RNA polymerase to specific initiation sites and are then released. Extracytoplasmic function (ECF) sigma factors are held in an inactive form by an anti-sigma factor until released, although no anti- sigma factor is known for this protein (By similarity). Regulates the promoter of SigI, may not be autoregulated.

Probable transcriptional regulatory protein (probably LysR-family); Rv0377, (MTV036.12), len: 321 aa. Probable transcription regulator, lysR family, showing similarity with many hypothetical transcriptional regulators lysR homolog e.g. P32484|YEIE_ECOLI|M89774 hypothetical transcriptional regulator from Escherichia coli (293 aa),FASTA scores: opt: 265, E(): 4.9e-11, (28.6% identity in 266 aa overlap). Also similar to Rv2282c from Mycobacterium tuberculosis. Contains PS00044 bacterial regulatory protein lysR family signature. Seems to belong to the LysR family of transcriptional regulators.

Two component DNA binding transcriptional regulatory protein TcrA; Member of the three-protein two-component system HK1/HK2/TcrA.

Rv0195, (MTV033.03), len: 211 aa. Possible two-component response regulator, luxR family, similar to many e.g. U00008|ECOHU49_15 regulatory protein narP from Escherichia coli strain K12 (225 aa), FASTA scores: opt: 232, E(): 7.3e-09, (29.2% identity in 219 aa overlap). Start chosen by similarity. Contains probable helix-turn-helix motif at aa 166-187 (Score 1164, +3.15 SD).
